The truck is a '56-F100 big window with 8' bed.
I've owned the truck for over 25 years, and mechanically it's very sound.
I finally want to address the rust, and am trying to decide if it makes sense for me to learn how to do this work on my truck, or if it makes more sense to farm it out to an experienced hand. I do know of a guy who works at a body shop near me. He came highly recommended by a car guy I know, although I don't have personal experience with him. His boss will allow him to do the work on his own time in the shop. I do have a 110v Miller mig welder, but no other welding or body working tools.

Are these rust areas pretty routine to repair?

 

What kind of money are we talking about to repair to the areas in the photos?
Or maybe its better to ask how many hours on average?

 

IMHO, floor panels are pretty easy to repair......the key is to make sure the vehicle is level in all directions (using jack stands, etc. as you do not want any movement), assuming your have replacement panels, small sections with rust, just section those areas out and use those as templates for cutting out the replacement sections from the new panels....if the whole pan needs to be removed, after you remove the entire existing pan, get a helper to assist setting the pan inside the vehicle and realize that a little massaging is likely to be required....but nothing that you can't handle.

 

How many hours would that take someone who knew what they were doing?

 

partial floor pan....a day......the entire floor pan, a weekend.

 

some one that knows what there doing can change out both sides (complete) in 5-8 hrs thats including cab supports, ive done hundreds over an almost 40yrs span. Fairly easy job, tackel it yourself, you can do this. GOOD LUCK with your build.

 

Not that knowledgeable, suggest inspect the entire vehicle, compile a list of body sheet metal components that should be repaired or replaced, then decide to what extent willing to spend, to include time and labor. Imagine Dennis Carpenter, Mac's antique Ford parts, Carolina Classic's, to name a couple, have the majority of the sheet metal but not cheap, replacing a section of a floor pan is considerably cheaper than the entire pan, also once the cab mounts are exposed may find they should be replaced, etc.

Personally, I would consider replacing floor pans a learning experience, now when it came to fabricating, welding cab mounts, or replacing sections of door panels, etc., even though I own a MIG, may require more experience than I have, but probably worth a try??

If U have an ebay account suggest set up daily email notices when seller's post items that fit your application?

Posting link to article, imagine if run a search there are several video's on topic? By opening any of the photo's brings up a gallery with brief description.
